To all whom it may concern:

Be it known that I, ROBERT O. HENDRICK- soN, a citizen of the United States, residing Portland, in the county of Multnomah useful Improvements in Gearing, of which the following is a specification.

This invention relates to gearing and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

The'object of the invention is to provide a simple and eflicient gearing capable of use I as a steering gear for traction engines and 1n the illustration of the invention the gearing is so applied. In engines of this class, especially the higher power engines, the power necessary to handle the steering apparatus is such as to be inconvenient for hand operation.

In 'thepresent invention, means are provided for utilizing the power of the engine for operating the steering member. Preferably, the mechanism is so arranged that this may be thrown into and out of action by the steering wheel. The construction is also arranged so that the steering wheel may be utilized for hand steering if desired.

The invention is illustrated in the accompanying drawings as follows:

Fig. 3 a central section showing the steering Wheel, post and steering mechanism immediately attached thereto and a fragment of the driving wheel in elevation. Fig. 4: a similar section of the steering post, and steering wheel, with the steering wheel in position for throwing in the power steering mechanism. Fig. 5 sections on the lines 5-5 and 5=-5 in Fig. 3.

The head 8 has the annular groove 11 in which is ar- Specification 'of Letters Patent.

ranged a flexible connection such as a cable or chain 12. The ends of this cable 12 are wound on the shaft 13 extending across the frame and carried cable 12 is wound on the shaft 13 in opposite directions so that as the shaft is turned in either direction, one end and wound up at the opposite end, thus. actuating the steering member through the action of the cable on the head 8.

A gear case 15 is carried by the bearing 16 on the shaft 13. This gear case is also provided with the bearings 17 in which the worm sleeve 18 is journaled, preferably by means'of a ball bearing as shown. The worm sleeve carries the steering worm 19 and the steering Worm -19 meshes the worm gear 20. The worm gear 20 is mounted on the shaft 13 and fixed thereon by a key 21. The Worm sleeve '18 is provided with the detents 22 at its upper end which are adapted to be engaged by the detents 23 on the steering post 24. ,The steering wheel 25 is fixed on the steering post by means of the screw 26. 1 A shaft 27 extends through the steering post, the steering post being in the form of a sleeve for this purpose, and also through the worm sleeve 18. The shaft the cable is paid out at bythe bearings 14. The

27 therefore forms a bearing for the post its upper end and this is adapted to enter the bayonet slot at the end ofthe steering post, this slot having the inwardly extending portion 29, lateral portlon 30 and the outwardly extending portion 31. It will be readily observed that by bringing the portion of the slots 29 into register with the pin 28, the steering post may be lifted on the shaft 27, bringing the pin 28 into the lateral portion 30. By turning the post, the pin can be brought into the portion 31 and then dropped into the socket formed by the portion 31. The portion 31 is of such depth that when the pin 28 is seated in the portion 31,- the detents 23 and 22 are maintained out of engagement aml at the same time, the

steering post is locked against turning on the turn the shaft 13 and actuate the steering.

member. When it is desired to throw in the power, the steering wheel is thrown into the position shown in Fig. 4. This disengagesit from the direct connection through the members 22 and 23 and the power mechanism is controlled fromthe steering wheel acting on the shaft 27.

The shaft 27 terminates in a crank 32 having a crank pin 33 which is rocked by the shaft 27. The crank pin extends into a block 34 and the block 34 is arranged in a groove 35 in the sliding clutch member 36. The sliding clutch member is locked against turning on the shaft 37 by a spline and groove 37 and is free to move axially on the shaft. The sliding clutch member has the conelsurfaces 38 at its ends which are adapted to be thrown into engagement with the cone surfaces 39 on the opposing clutch members and the members having the cone surfaces 39 are fixed on the gears 40. The gears 46 *are journaled on the shaft 37 and engage a gear 41 fixed on the end of the worm sleeve 18. l

The shaft 37 is continuously rotated in one direction. It will be readily observed that by throwing the clutch member 36 into engagement with the gear 40- at one side, a reverse movement is given to the worm sleeve from what is given to the worm sleeve when the clutch member is thrown into engagement with the opposite gear 40. By tin-ping the shaft 27, the crank 32 is oscillated and this operating through the block 34 throws the sliding clutch member 36 into engagement in .either direction so as to give the direction to the worm sleeve desired. The sliding clutch member 36 has the sockets 36" at each end in which is arranged a collar or pressure block 36". Screws 36 are screwed through the pressure blocks 36* and into the clutch member 36. Coil springs 36 are arranged around the screws and between the bottoms of the sockets36 and the pressure blocks 36*. The screws are turned in so as to adjust the blocks36 to fill the space between the gears 40. Sockets are arranged in the blocks 36 for the headsof the screws 36, and are of sufficient depth to permit the movement of the block 36 with the screw 2. suflicient distance to throw the cone surfaces 38 into engagement with the cone surfaces 39, but as soon as the shaft 27 is released, the spring 36 which is compressed, will throw thefclutch out of engagement, and the springs operating on each of the blocks 36 will hold the sliding clutch member in a neutral position.

The gears 40 have the extended hubs 42 which operate in bearings 43 in the gear casing 15. The shaft 37 is journaled in these hubs. Apulley 44 is fixed on the end of the shaft 37 by means of a pin 45 and a belt 46 drives the pulley 44 from a pulley 47 on the engine shaft 48. In this way, it Wlll be seen that the shaft 37 will be rotated at all times while the engine is in motion.

The position ofthe engine is indicated by ing 55 operating on the-steering post holding it against rotation on the shaft.

lVhile I have shown the sliding clutch member 36 as being operated from the steering wheel, it will be understood that in the broader phases of my invention, the sliding clutch member may be operated by other agencies, especially, a furrow follower. In

the 'drawingsa socket 56 is shown for the insertion of a crank shaft for operating the sliding clutch member in this manner. Where this is utilized, thesteering wheel is simplyplaced on the pin 28 and thus drawn out of action except for the slight movement that the sliding clutch member gives it.
